A rod, $180$ mm long and $590$ mm$2$

in cross$-$section, made of this alloy and

operating at $120$C$,$ is not to creep more than $5$ mm in $3000$ hours. Calculate the

maximum admissible axial load which can be applied for the safety factor $2\mathrm{.}5.$ The rod is made from a aluminium alloy and is subjected to a temperature of$120$ degrees. Please can you explain every step of this question.
